A SAR translation strategy adopted for the discovery of tetrahydroisoquinolinone (THIQ)‐based steroidomimetic microtubule disruptors has been extended to dihydroisoquinolinone (DHIQ)‐based compounds. A steroid A,B‐ring‐mimicking DHIQ core was connected to methoxyaryl D‐ring mimics through methylene, carbonyl, and sulfonyl linkers, and the resulting compounds were evaluated against two cancer cell lines
用于发现基于四氢异喹啉酮 (THIQ) 的类固醇模拟微管干扰物的 SAR 翻译策略已扩展到基于二氢异喹啉酮 (DHIQ) 的化合物。类固醇 A、B 环模拟 DHIQ 核心通过亚甲基、羰基和磺酰基接头连接到甲氧基芳基 D 环模拟物,并针对两种癌细胞系评估所得化合物。羰基连接的DHIQs尤其表现出显着的体外抗增殖活性(例如,6-羟基-7-甲氧基-2-(3,4,5-三甲氧基苯甲酰基)-3,4-二氢异喹啉-1(2 H)-酮(16 g ):在 DU-145 细胞中的GI 50 51 n M )。DHIQ的广泛的抗癌活性16克证实在NCI 60细胞系测定给出33 n中的平均活动中号。此外,6-羟基-2-(3,5-二甲氧基苯甲酰基)-7-甲氧基-3,4-二氢异喹啉-1(2 H )-one ( 16 f ) 和16 g及其氨基磺酸衍生物17 f和17 g ( 2-(3,5-二甲氧基苯甲酰基)-7-甲氧基-6-氨磺酰氧基-3
